Notes

Spawning up this docker stack will provide you with:

• A containerized Grafana web instance runnning on the default port TCP/3000
• A containerized Telegraf instance that fetches data points from your docker host server
• A containerized InfluxDB instance for storing Telegraf data, which can be defined in Grafana as datasource (just specify http://influxdb:8086). Default database is telegraf. Default username is telegrafuser. Default password is MyStrongTelegrafPassword. Defaults can be changed in /volume-data/influxdb/init/create-database.iql.
• A containerized Promtail instance that can fetch various log files (bind mounted into the promtail container from your docker host server) and send them into the Loki container (e.g. /var/log/auth.log or your Traefik reverse proxy logs)
• A containerized Loki instance for storing Promtail log data, which can be defined in Grafana as datasource (just specify http://loki:3100). No authentication enabled per default.

Finally, after configuring InfluxDB and Loki as datasources on Grafana, you can just import the provided Grafana_Dashboard_Template.json dashboard template YAML file in Grafana by browsing http://127.0.0.1:3000/dashboard/import. Your dashboard will look like the following:
